I noticed that it is becoming more common to see positions for "low-level" Rust engineers here in Tokyo. Some recruiters asked me about "core" and "no_std" Rust. That is really cool to see! (Tho, I think most positions are just for one company)

I am curious about what people from the USA think of Pluribus. At home we all think Carol is wrong and the villain of the show, thinking only about herself and never ever thinking in putting herself in other people's shoes.

The International Criminal Court is ditching Microsoft Office, saying it’s too dependent on US tech, in favor of Open Desk, a German open source alternative.
The move comes after Microsoft revoked ICC head Karim Khan’s email access when he was sanctioned by the US for the warrant against Netanyahu.

🦀 I've improved the implementation behind all the string formatting macros in Rust: println, panic, format, write, log::info, etc. (Everything using format_args!().) They will compile a bit faster, use a bit less memory while compiling, result in smaller binaries, and produce more efficient code! 🎉

Turns out you can communicate across containers via 63-bits of available space in a shared lock you acquire on /proc/self/ns/time that all processes have access to.
No networking required. The post has a demo of a chat app communicating across unprivileged containers.

If you want to use LLM for everything at very least be transparent about it. I see now some people using LLM to show they are smart without telling other folks. The issue? If I wanted to discuss something with ChatGPT, I would have done it and I would pay attention to hallucinations.

Some cyber security software allow arbitrary command execution, which makes it a backdoor running in all companies computers. Those softwares should be audited as well, to make sure they create a paper trail of any command and only execute authorized instructions.
New Policy Analysis: Europe's cybersecurity heavily relies on the United States.
My key points:
1. Europe's dependencies on the US in the field of cybersecurity extend well beyond software updates, SaaS, and cloud services and would persist even if a EuroStack were developed. /1
